I'm looking into a laptop and the screen has a lot of artifacts all over the place, but only sometimes. It's really random because sometimes even at startup it will be either completely clear or almost unreadable. Sometimes it will be fuzzy and gradually worsen then clear up and fuzz up again over time. If I unplug the battery it seems to terribly worsen and so I figured it had to do with that. In HWMonitor the laptop's temperatures run fine, but the battery's wear level is at 42% (edited: realized my conversion was off haha) Should I replace the battery or is something else the problem? 42% seems ludicrously high
